Claims

[Scope of utility model registration request]

A rocking body having a rotating part for mounting a belt at one end and a threaded part at the other end, the swinging body being swingably supported using the threaded part as a fulcrum, and screwed into the threaded part;
A slide member displaceable in the axial direction of the threaded portion and non-rotatable around the axis; and the slide member is biased in the axial direction of the threaded portion to frictionally engage the threaded member. a biasing means for bringing the rotating part of the rocking body into adjustment elastic contact with the belt, a first chamber and a second chamber are formed in a sealed manner on both sides of the slide member, and a damping device is provided in the first chamber and the second chamber. An autotensioner characterized in that the oscillator is filled with liquid to prevent vibrations.
